The ignition wire that would normally go to the + side of the coil on your Dodge now needs to go to the + terminal on your GM electronic ignition. If you have a tach, there should be a connection place on the GM dist to connect your tach lead that normally would have connected to the + coil wire on the Dodge stuff.

Can't help you on that GM 1 wire alt. They call it a 1 wire, but most I've seen have 2 wires, so I'm confused. LOL! Gene
